Medical lasers are devices that are used by precisely focusing light sources on certain areas to treat and remove tissues. Laser lights have a fixed wavelength as opposed to normal light sources, therefore they are able to focus in a narrow beam and create a very high-intensity light. Since lasers are able to focus on small areas, they can be used to accomplish precise surgical work.
With proper use, lasers allow the surgeon to accomplish more complex tasks, reduce blood loss, decrease postoperative discomfort, reduce the chance of wound infection, and achieve better wound healing.
As with any type of surgery, laser surgery has potential risks. Risks of laser surgery include incomplete treatment of the problem, pain, infection, bleeding, scarring, and skin color changes.
Laser surgery uses non-ionizing radiation, so it does not have the same long-term risks as x-rays or other types of ionizing radiation.
Lasers are used in many types of surgical procedures. Some examples include
Lasers have been used in dentistry since 1994 to treat a number of dental problems. Yet, despite FDA approval, no laser system has received the American Dental Association's (ADA) Seal of Acceptance as an alternative to more traditional treatment. That seal assures dentists that the product or device meets ADA standards of safety and efficacy, among other things. The ADA, however, states that it is cautiously optimistic about the role of laser technology in the field of dentistry. These lasers are different from the cold lasers used in phototherapy for the relief of headaches, pain, and inflammation.
Refractive surgery is the term used to describe surgical procedures that correct common vision problems (nearsightedness, farsightedness, astigmatism and presbyopia) to reduce your dependence on prescription eyeglasses and/or contact lenses.
Currently, a laser procedure called LASIK (LAY-sik) is the most popular refractive surgery performed in the United States. But there are other types of refractive surgery — including other laser procedures and intraocular lens procedures — that might be an even better choice for you, depending on your needs
A laser is a highly focused beam of light. A doctor can use a laser to treat varicose veins. Laser heat damages a vein, which makes scar tissue form. This scar tissue closes the vein. A closed vein loses its source of blood and dies. After a year or two, the vein is likely to disappear.
